I like these ideas, Jonathan, but wonder whether the two concepts should be orthogonal (possible implementation : treat the value of \XeTeXinterwordspaceshaping as a bit mask, such that \XeTeXinterwordspaceshaping = 1 would be for SIL's Awami Nastaliq, etc., \XeTeXinterwordspaceshaping = 2 would be for Hoefler Italic, etc., and \XeTeXinterwordspaceshaping = 3 would be for both). This would also allow future extensibility without compromising backward compatibility.
